Medo, I never disputed when the pic was taken, purely said that it was the end of the "original" extension from Vic Sq.
Also I wouldn't doubt the convention centre would have pressured for access to one of it's car parks (Interesting as it's government owned also)
The one thing you'll have also noticed is that 95% of the traffic that uses the lane uses it as a 'U' turn and not for car park access.
Also because of the loss of the "parking" lane on the north side of North tc to the west of the bridge, access to the convention centre loading dock has become a total nightmare during 'move in' and 'move out' times for events at the centre.
And don't I know it!! I've had to hold semi's back somewhere in Thebarton because the police wouldn't allow them to wait on North Tc. It's bad enough problem to warrant the convention centre to plan to increase the loading dock area. This will mean using the space between the bridge and the current loading dock (by further undergrounding the railway station)
Anyways I agree the single line section became a joke when the 2nd extension was done.
And knowing someone (relative) on the 'inside' who has revealed that the points have become a "maintenance nightmare" since originally installed, the sooner they are removed the better. They are now no longer needed since the turn back was constructed closer to West Tc.
